The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Navy Cross to Commander William Alfred Stevenson, United States Navy, for extraordinary heroism in the line of his profession as Commanding Officer of the U.S.S. ASPRO (SS-309), during the FIFTH War Patrol of that submarine in enemy controlled waters of the Pacific War Area. Daring and tenacious, Commander Stevenson successfully penetrated strong enemy escort screens while operating in hazardous coastal shoal waters to launch well planned and executed torpedo attacks against enemy shipping which resulted in the sinking of four enemy vessels totaling 25,500 tons, and the damaging of an additional enemy ship of 10,000 tons. Despite depth-charges and aerial bombing he employed skillful evasive tactics and brought his ship to port. His devotion to duty, courage, and inspiring leadership reflect the highest credit upon Commander Stevenson and the United States Naval Service.
